Haha, I had to do Internet research to make sense of Fenric too, but I'm glad I did, and I think it's a very rewarding serial to rewatch once you've got it all straight in your head. Because the lack of connective tissue--and the minor niggle of "Enigma machines and natural language translation don't work like that, holy hell Fenric, for such a geeky and intelligent serial that is a really embarrassing bit of Magic Science"--are really its only flaws. And once you more-or-less know what's going on you can sit back and dig into the layers upon layers of themes and allegory and gah I love Fenric so much. It's like a demented six-way chess match where the pieces keep changing sides and then they set the chessboard on fire. Twice.
